b.
Mammal Activity-Deer, coyote and fox activity on or near the airfield is year round. Extreme caution should be used for landing or takeoff during the hours of darkness.
c. Bird Watch Conditions are as follows:
(1)
LOW - Normal bird activity on and above the airfield with a low probability of hazard.
(2)
MODERATE - Increased bird population in locations which represents an increased potential for strike. Requires increased vigilance by all agencies and supervisors and caution by aircrews.
(3)
SEVERE - High bird population on or immediately above the active runway or other specific location that represents a high potential for strike. Supervisors and aircrews must thoroughly evaluate mission need before conducting operations in areas under condition SEVERE.
d. BASH PHASES:
(1) BASH Phase I - All months not designated as Phase
II. Wildlife activity is generally LOW during these periods with the primary threat resulting from small species of birds such as mourning doves, starlings, kestrels, and horned larks.
(AFFSA/AFFSA)
(2) BASH PHASE II - In effect by NOTAM as determined by airfield surveillance and risk assessment, Phase II is most likely to occur in March-April and September-October. Bird activity may increase during these periods due to the presence of migratory waterfowl such as mallards and Canada geese. Short periods of MODERATE or SEVERE may occur during these periods.

1. NOISE ABATEMENT - Strict adherence to departure procedures and expeditious climb to assigned altitude are required to minimize noise impact on surrounding areas. LOW
TRANSITIONS PROHIBITED. Visual approach shall also be prudently planned and executed to minimize noise impact. (USN/NAVFIG)
2. DEPARTURES -
a.
RUNWAY 07 and 14 - Follow published departure procedures. Tactical/high performance jet aircraft shall not turn on course prior to 3000' MSL.
b.
ALL RUNWAYS - Afterburner take-off permitted only when required by NATOPS or written standard operating procedures. Afterburners must be secured no later than the field boundary.
(USN/NAVFIG FIL 0052-08)
3. BIRD HAZARD ACTIVITY - Heavy bird activity, greatest from mid-February to end of August. Greatest risk is from the Great Blue Herons crossing the approach/departure centerlines of Rwy 25 and 31 enroute to feeding grounds to the E in Dugualla Bay and Skagit River Flats. When low tides are present, expect increased Heron activity on the approach/departure centerlines of Rwy 25 and 31. Use extreme caution 1 hour prior to and 1 hour after sunset from ground level to 200’ AGL. Great Blue Heron strikes have occurred as high as 2300’ as far as 4 DME.
Condition Intensity
RED SEVERE (Immediate)
YELLOW MODERATE (Probable)
